Specification of Letters Patent.

Patented July as, 1922.

Application filed January 7, 1921. Serial No. 435,614.

To all whom it may concern:

Be it known that I, HARRY A. Smart, a citi- Zen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Signal Devices for Railway Train- Order Semaphores, of which the following is a specification.

This invention relates to improvements in railway signal devices, and it pertains more particularly to a device for use in connec tion with the display and operation of train order semaphores.

The object of the invention is to provide a system in signalling of this character, in which the train dispatcher will be automatically informed that his order to an operator on the line has been carried into effect.

Another object is to provide means whereby the operator will be informed that the signal semaphore thrown into certain posi tion by him, still remains in that position.

The invention contemplates the placing of a switch in the line, so connected that the setting of the semaphore manually, as is usual, will close two circuits, one to the train dispatcher and the other to the operators table, in other words, an inside and an outside line are both energized through the medium of this switch when the operator sets the semaphore.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which Figure 1 is a diagrammatic view showing the indicators in the positions of the train dispatcher and the operator, and showing two operators positions or stations.

Figure 2 is a detail view of the switch.

The numeral 1 designates an indicator, located in the train dispatchers oflice and 2 the indicator in the operators station. The numeral 3 designates a semaphore, mounted on an upright 4 and provided with an operating rod 5 leading to any suitable hand operated lever 6.

On this rod, I form an arm 7 and this arm 7 is attached to the movable member 8 of a switch. This switch may be of any desirable form, and I have shown a device comprising a frame 9 in which are located two vertical posts 10 adapted to move in the frame. One contact member is carried by this movable part and the other in the form of spring members 11 are mounted inthe frame portion. Additional or secondary contacts are provided in the form of spring members 13 secured to the frame member and adapted for contact by a portion 14; of the movable switch member, so that when the switch is actuated, both the inside and outside circuits, shown at 15 and 16 respectively, are closed and this two-fold circuit closing will effect a signal indicator in each line, one in the line 16, which would be the train dispatchers and the other in the line 15, which would be the operators.

In action, when the train dispatcher issues an order to the operator at station No. 1, the operator actuates the semaphore, throwing it to the desired position. The actuation of this semaphore will be accomplished through the movement of the rod and arm and this movement will actuate the switch to closethe two circuits, 15 and 16; the one to the train dispatchers oflice informing him that his order has been executed, and the other to the operators table, indicating that the semaphore is at the desired position.

The numeral 18 designates a circuit breaker, in the form of a key, in the line 16,

and when the operator has carried out the order to throw the semaphore, this key is actuated to open the line beyond his station, and this action of actuation of the key will register on the indicator No. 1, informing the train dispatcher that the line is open and permitting him to communicate with any other point along the line.

It will therefore be noted that with this system, the train dispatcher is automatically informed that his order to the operator has been carried out and the element of uncertainty as to whether or not certain signals are displayed is eliminated and that when the circuit breaker is actuated in the outside circuit the line is deenergized, so that it will be in operative condition, while the inside circuit will continue to show the indication at the danger signal.

It will be noted therefore, that, while the indications on outside and inside circuits are given simultaneously, the secondary operation, through the circuit breaker, will clear the outside circuit, but will allow the other or inside circuit to remain at danger indication.

It is understood that the drawing forming a part of this application is more or less diagrammatical, and that the details and arrangement of parts may be varied, multiees see electric switch operatively connected with the semaphore, an inside circuit and an outside circuit, both of which are, connected with the switch, whereby indications on both circuits may be given simultaneously, and a circuit breaker in the outside circuit, whereby the outside circuit may be deenergized while the inside circuit is left at the 20 indication originally given.

In testimony whereof I affix my signature.
